Volume Calculator
Calculate the volume of common three-dimensional shapes with one tool. Choose a cube, rectangular prism, cylinder, cone, sphere, rectangular pyramid or triangular prism, select the measurement unit and enter the required dimensions. The calculator returns the volume in the selected cubic unit and also converts the result to cubic meters, liters and US gallons. This makes the tool useful for geometry, containers, tanks, construction quantities and practical capacity estimates.
How to use the Volume Calculator
- Choose the three-dimensional shape you want to calculate.
- Select the unit used by all entered linear dimensions.
- Enter the dimensions requested for the selected shape.
- The calculator applies that shape's geometric volume formula.
- The primary result is shown in the selected cubic unit.
- The same result is converted to cubic meters and liters.
- A US-gallon equivalent is also displayed when a liquid-capacity comparison is useful.
Examples
Rectangular prism
A box 10 m long, 5 m wide and 3 m high has a volume of 150 m³.
Cube
A cube with side length 4 has volume 4³ = 64 cubic units.
Cylinder
Cylinder volume is πr²h, so both radius and height determine capacity.
Sphere
Sphere volume uses 4/3 × π × r³, making radius the only required dimension.
Cone
A cone has one-third the volume of a cylinder with the same circular base and height.
Frequently asked questions
What shapes does this volume calculator support?
It supports rectangular prisms, cubes, cylinders, cones, spheres, rectangular pyramids and triangular prisms.
What is the volume of a rectangular prism?
Multiply length × width × height.
What is the cylinder volume formula?
Cylinder volume is π × radius² × height.
What is the sphere volume formula?
Sphere volume is 4/3 × π × radius³.
Can the calculator convert volume to liters?
Yes. It converts the calculated volume through cubic meters and displays the equivalent liters.
Why are volume units cubed?
Volume measures three dimensions, so a linear unit such as meters becomes cubic meters when length, width and height are multiplied.
Can I use feet or inches?
Yes. The calculator supports meters, centimeters, feet, inches and yards as input dimension units.
